Victron MultiPlus 12/3000/120-50 120V UL (PMP122301102)

The Victron MultiPlus 12/3000/120-50 120V UL is the premier all-in-one power solution for North American 12V systems. This UL 1741 and UL 458 certified inverter/charger combines a 3000VA pure sine wave inverter, a high-capacity 120-Amp adaptive battery charger, and a lightning-fast 50A automatic transfer switch in a single compact enclosure. Whether you are powering a luxury RV, a marine vessel, or a remote off-grid cabin, the PMP122301102 provides the "no-break" reliability required for sensitive electronics and heavy motor loads.

Core Features & Technology

• Uninterrupted AC Power (UPS): In the event of a grid failure or shore power disconnection, the inverter activates in less than 20ms, ensuring computers and sensitive equipment continue to run without disruption.
• Hybrid PowerAssist: Prevents overloads from limited AC sources (like a small generator or 30A shore power) by boosting the output with battery power when peak demand occurs.
• Dual AC Outputs: The main output provides UPS functionality, while a second output operates only when AC input is available—perfect for heavy loads like water heaters that shouldn't drain your batteries.
• Adaptive 4-Stage Charging: The 120A charger uses advanced software to fine-tune the charge process based on battery condition, including a dedicated 4A trickle charge for a starter battery.
• Scalable Power: Up to 6 units can operate in parallel to achieve higher power output, or be configured for split-phase and three-phase operation.
